ANDREW C. BAKER, OF ALBION, MICHIGAN.

DUMP-WAGON.

Specification of Letters Patent.

Patented July *7, 1914.

7 Application filed October 18, 1913. Serial No. 795,918.

To all whom it may concern Be it known that I, ANDREW C. BAKER, a citizen of the United States of America, residing at Albion, in the county of Calhoun and State of Michigan, have invented certain new and useful Improvements in DumpWagons, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to dump wagons and more particularly to certain improvements in connection with my Patent 967154,

granted August 16, 1910.

My invention aims to provide positive and reliable means, in a manner hereinafter set forth, for expeditiously opening and closing the discharge doors of the wagon body.

My invention further aims to provide a door Operating mechanism that is located where it can be easily operated without subjecting the discharge doors or gates of the dump wagon to stress and strains, the connection with the doors or gates being such that they are supported in a horizontal position against accidental displacement when the vehicle is loaded.

With the above and other objects in view, the invention resides in the novel construction, combination and arrangement of parts to be hereinafter specifically described and claimed.

Reference will now be had to the drawings, wherein- Figure 1 is a longitudinal sectional view of a dump wagon in accordance with this invention. Fig. 2 is a cross-sectional view of the same. Fig. 3 is a rear end view of the wagon, and Fig. 4 is a view of the front end of the wagon.

In the drawings 1 denotes a conventional form of running gear'and arranged upon the running gear are front and rear platforms 2 and 3. These platforms support the ends of side walls 4 forming the sides of a box adapted to containdu'mpab-le material. The side walls 4 are connected by inclined end walls 5 and arranged upon the upper edges of the walls 4 and 5 are the walls 6 and 7 of an extension frame adapted to increase the capacity of the box. The walls 6 are stationary and are held by straps 8 or other fastening means, carried by the walls 5. The walls 7 are disposed at an angle and at the ends of said walls are inwardly projecting V-shaped arms 9 that are pivotally connected, as at 10 to the inner sides of the walls 6. The walls 7 can be swung upwardly relatively to the side walls 4 of the box and it is through the medium of the walls 7 that a heaped load can be discharged.

Arranged upon the front and rear platforms 2 and 3 are longitudinally alining bearings 11 and mounted in these hearings is a central tubular hinge member 12. Loosely mounted upon this member are the strap hinges 13 of center bottom doors or gates 14.

Connected to the lower edges of the side walls 4 by hinges 15 are side doors or gates 16 that cooperate with the center door or gates 1.4 in forming the bottom of the box. The doors 14 and 16 are adapted to swing downwardly whereby the contents of the box can be quickly discharged, and as a shield for the central hinge member 12, the walls 5 of the box are connected by a longitudinal deflector 17.

The side walls 4, at the ends thereof, are provided with transversely alining bearings 18 and journaled in said bearings are rock shafts 19 and 20. Mounted upon the rock shaft 19 are cranks 21, 21 and 22, the cranks 21 and 21 having chain connections 28 with the rear ends of the discharge doors 14 and 16 The single crank 22 is connected to a chain 24 that extends under a sheave or grooved pulley 25. revolubly supported by a hanger 26 forming a part of the bearing 11 upon the rear platform 3. The chain 24 extends through the central tubular hinge member 12 and under a sheave or pulley 27,

journaled in a hanger 28 forming part of the bearing 11 upon the forward platform 2. The chain 24 has the forward end thereof connected, as at 29, to a yoke 30, said yoke having its ends loosely mounted in strap bearings 31 provided therefor upon the forward platform 2.

The rock shaft 20 has a set of bell. cranks 32 that are connected by chains 38 to the forward ends of the discharge doors 14 and 16. The rock shaft 20 also has a single crank 34 that is connected by a chain 35 to the yoke 30.

The forward edge of the platform 2 has bearings 36 for the trunnions 37 of the looking lever 38. The upper end of the locking lever 38 has an ofiset portion 39 to receive the tread bar 40 of the yoke 30, whereby said yoke can be locked with the discharge doors 14 and 16 in a closed position. The

. gas illustrated in Fig.

upper end of the locking lever 38 terminates in a tread piece 41 which permits ot the driver of the vehicle quickly swinging the locking lever out of engagement with the yoke 30. The lower end of the locking lever v 7 doors 14 and 16 are locked in a closed podoors 14 and 16.

sitio'n and either one of the levers 38 or 45 can be used for releasing the doors 14 and 16. To quickly discharge the contents of the box it is only necessary to press upon the tread piece 41 of the lock lever 38. This is best accomplished by holding the lever 45 against the yoke 30 until the locking lever 38 has been shifted clear of the yoke, and then by releasing the lever 45 the discharge doors 14 and 16 will quickly open. To gradually discharge, the load within the box the lever 45 is held onto and the yoke 30 allowed to gradually swing and lower the The levers '38 and 45 are located centrally of the forward platform 2 in proximity to a d'rivers seat '46, and the arrangement of the levers is such that the discharge of material from the box of the wagon can be easily controlled. The yoke 30 serves functionally as a foot rest fora driver and cannot be accidentally shifted by reason of the locking lever 38 being held normally in engagement therewith by the compression spring 43.

\Vhile in the drawings there is illustrated a preferred embodiment of my invention, it is to be understood that the structural elements are susceptible to "such changes, as in the size, shape and proportion as falls Within the sco'peof the appended claims.

, "WhatI claim is 1. In a dump wagon, 'a box, a tubular hinge member longitudinal of said box,

(Etfiies or this patent ma be 'ob'tai'ncd :fo r five cents each, t aaares'i'n' the commissioner or Patents,

hinged center doors carriedthereby, side doors carried by said box and cooperating through said member whereby the doors can be evenly moved; 2.11m dump wagon, a box, platforms at the ends of said box,a tubular hinge member supported by said platform, hinged center bottom do'ors .carr-ied by said member, hinged side bottom doors carried by said bo'x,'rock cranksh'afts connected to said doors, and "a pivoted yoke supported by one of said platforms "and having connection with "said crank shafts with one of said connec'ticns extending thr'o'dgh said member.

3'; In a dump wagon, a box, a tubular hinge member arranged longitudinally of said box, discharge doors hinged thereon, sidedoors carried by the said box and co' operating with said discharge doors in forming the bottom of said box, and means opera'ta'ble at "cne end of said box with a connection through said member to the op posite end of said box for evenly moving the ends of the said doors.

4. In a dump wagon, a box, 'atubular' hinge member arranged longitudinally of said box, "discharge doors hinged thereon,
